| description | The invention relates to the technical field of support installation, and discloses a lifting device capable of adjusting the height of a video conference display. The lifting device comprises a top plate, a set of connecting frames and a pedestal. A set of circularly-structured contraction grooves are formed in the middle position of the upper side of the pedestal in a downward mode. A base plateis fixedly installed at the inner bottoms of the contraction grooves. The upper side of the base plate is connected with a shear fork mechanism. A lifter used for controlling the shear fork mechanismto be lifted up and down is arranged on the lower side of the bottom of the shear fork mechanism. The top plate is fixedly installed at the top of the shear fork mechanism. The set of the connectingframes are fixedly installed on the rear side face of the display. The insides of the connecting frames are fixedly connected with a set of driven gears. The right sides of the driven gears are engaged with a driving gear. The |
